Abstract
Official abstract text for this publication.
A method for accessing a memory includes: utilizing a Flash memory to perform a plurality of sensing operations with a plurality of different sensing voltages respectively corresponding to the plurality of sensing operations; according to the plurality of sensing operations, generating a first digital value of a Flash cell of the Flash memory; according to the plurality of sensing operations and the first digital value, generating at least a second digital value of the Flash cell; and obtaining soft information of the Flash cell according to the second digital value. The first digital value and the second digital value are used for determining information of a same bit stored in the Flash cell, a number of possible bit(s) of the Flash cell directly corresponds to a number of possible states of the Flash cell, and the obtained soft information is used for performing soft decoding.
